R0390S2 - SIDE STIFFENER R (IF18-3/CARBON)

Spring holder for R0412 long life clutch spring (long type/11mm).
 The surface is silver to distinguish it from the R0251-06 clutch spring holder (black).

The material and coating have been updated to significantly improve crash resistance and durability compared to the standard items. The shaft is highly durable and resistant to scratches even after long periods of use.

Weight has been reduced by F:0.3g R:0.5g, removing this unnecessary material has improved rotational balance. Reduced clearance in the thrust direction helps maintain wheel stability during running.

Spare part for R0390.

In addition to the conventional 9, 10, and 11mm, the new 8mm is now available as a set with the necessary parts for installation!
 By using 8mm, the outer wheel has more angle allowing for a wider range of settings.
 R0259 Aluminum Servo Saver Set (top mount) is required.

Shock mounting is 1.5mm outside from the R0355N included in the kit.

For rear only

Mounted on the front portion of the upper deck to increase rigidity and steering response. Rigidity can be adjusted by using a combination of fixing screws.

New 0.8 module spur gear designed for high precision, high strength, and high durability. Gear specifications have been redesigned to provide uniform backlash for all tooth number combinations. The tooth width of the 2nd gear spur gear (R0409T56-T58) has been increased by approximately 12% to achieve even higher strength and durability. *Cannot be used in combination with conventional 0.8 module spur gears (R0247-60-62 and R0248-56-58) to prevent gear breakage. *Pinion gears for IF18-3 (R0384T18, R0384T19, R0385T23, R0385T24) must be used.

Prevents the side belt from falling off when a heavy load is applied to it.

Revival of the plastic front body mounting plate that was a standard item on the INFINITY 1/8 racing first model and IF18. It subtly reduces the powerful front downforce from the body for smoother steering characteristics.

Lightweight and rigid flat head screw made of titanium, with the optimum length for installation of 2-speed spur gears for more secure tightening.

A brass battery plate that concentrates the weight in the center of the car body and increases the chassis rigidity achieves higher driving stability. In particular, it is easy to control on a high-grip road surface and prevents traction roll.
